Figure 10: Menu Navigation and Feedback
Here is a table of available configuration gestures, and what each does:
Reset Level Flight and Trims
: 1 Toggle (up-down if the switch is presently down, or down-up if presently up)
After changing the trims on your controller or mounting orientation, you must let the Guardian know about this change so it can best control your airplane. Without this
information, 3D Heading Lock will not work and stabilization performance will be degraded.
To update the trim and level flight information for your controller in the Guardian, quickly toggle the Mode Switch back and forth once within the first 15 seconds after
power-on. You will know that the level flight orientation and trims have been reset when the servos both twitch once and then immediately return to normal movement.
If no twitch occurs when executing Reset Level Flight and Trims, it can either be because the switch gesture was not done quickly enough or within the first 15 seconds
following boot. Alternatively, if the Guardian is mounted too far off of level flight (greater than 25 degrees in either Pitch or Roll), the Reset Level Flight and Trims will
fail, presenting no servo twitch.
Reset Trims Only:
2 Toggles (up-down-up-down if the switch is presently down, or down-up-down-up if presently up)
Use this gesture to reset your trims without needing to also reset your level flight orientation.
To quickly update the trims of your plane in the Guardian, quickly toggle the Mode Switch back and forth two times within the first 15 seconds following power-on.
(Example: up-down- up-down) You will know that the trims have been reset when the servos both slowly twitch twice and then immediately return to normal movement.
Toggle Elevon Mixing:
3 Toggles (up-down-up-down-up-down if the switch is presently down, or down-up-down-up-down-up if presently up)
A shortcut method for switching between normal and elevon mixed airframes.
To quickly switch elevon mixing on and off without needing to go into the Radio Stick Menu or use the PC software, quickly toggle the Mode Switch back and forth three
times within the first 15 seconds after power-on. You will know that the mode has been changed when the servos both slowly twitch three times and then immediately
return to normal movement. After this, moving your control sticks will reflect the current mixing configuration.
This action will toggle from Normal or V-Tail Mode to Elevon Mode and from Elevon Mode to Normal Mode.
Enter Radio Stick Menu:
4 Toggles (up-down-up-down-up-down-up-down if the switch is presently down, or down-up-down-up-down-up-down-up if presently up).
Enters menu mode (described below).
Radio Stick Menu Operation
The Guardian 2D/3D Stabilizer has many advanced features that can be configured through the Radio Stick Menu.
Entering the Radio Stick Menu
Entering the Radio Stick Menu is done by powering the model with the Guardian connected and
quickly toggling the Mode/Config Switch back and forth four times within the first 15 seconds
following power-on. One second after the last switch movement, the menu will be invoked.
You will know that the menu has been invoked when the servos of your model stop their normal
stabilization deflections and instead perform a short twitch followed by no further movement.
Also, the status LED will blink in a two blink sequence when the menu is active.
Menu Navigation
Once in the menu, you will start at menu item #1 in the List of Features and Options section
below. The menu items can be navigated by deflecting the Aileron and Elevator control inputs
(your control stick). On a controller where moving the stick to the right and pulling it back results
in negative servo deflections (servo pulse width is shortened), flicking the Aileron input to the
right will increase the menu item number currently being edited, while flicking the Elevator input
forward increases the option value for the currently selected item in the menu.
Menu feedback is reported through the Aileron and Elevator servo outputs, as shown in Figure 10.
Each time a new menu item is selected by flicking the Aileron control, the Aileron servo will
“twitch” once, delay 1.5 seconds and then twitch rapidly a number of times that corresponds to the
current menu item number selected. After this, the Elevator servo will count up to the current option value number selected for that menu item. If a new option value is
chosen by flicking the Elevator stick, the Elevator servo output only will twitch once each time the value is changed, wait 1.5 seconds and then count up to the selected
option value number.
If you have your Aileron or Elevator directions reversed on your transmitter, then they will also be reversed as you navigate the menu!
If you have reduced the rates/deflection ranges configured on your transmitter for your servos, ensure that they are deflecting at least 50% in order for
the menu to detect their movements.
Exiting the Menu
To exit the menu, saving the settings that were changed, quickly toggle the Mode/Config switch back and forth once. (up-down or down-up) Once out of the menu, normal
servo deflections will start again, using the new settings.
To exit the menu without saving your changes, simply disconnect the receiver battery and repower the plane. The Guardian will boot up again with its previous settings.
Menu Example
Let’s say you want to set the 2D Heading Hold Gain (menu option 5) to a value of 6. First, toggle the Mode/Config switch 4 times, to enter menu mode, which starts at
menu option 1. Then, you will flick the Aileron stick to the right (or left, if your ailerons are reversed) 4 times, to reach menu option 5. Then, your Aileron should twitch 5
times, to indicate that menu option 5 is selected. And, your Elevator will twitch a number of times, indicating the present setting for the 2D Heading Hold Gain. Then,
flick your Elevator stick up or down, to increase or decrease the 2D Heading Hold Gain setting, until it reaches 6. At this point, the Elevator should twitch 6 times, which is
the desired setting. To save the new setting, toggle the Mode/Config switch once, which exits menu mode, and returns servo control.
List of Menu Features and Options
The following is an ordered list of all the options adjustable in the Guardian’s Radio Stick Menu, and from the PC software. Note that options 14 and higher are available
only via the PC software.
1.
Model Control Type
Enables internal mixing if needed. The Guardian expects only an unmixed servo control signal from the Rx.
1: Standard – Dual ailerons / flaperons are supported.
